Title: Effective value feedback-type thyristor phase controller
Inventor: HARITA KOUJI
IPC: G05F1/455
Filed: 1978-10-18
Abstract: PURPOSE: To ensure the high-stability and high-accuracy control by feeding the effective value voltage back to the amplifier circuit, thus realizing an effective application to the electric furnace or the like.  
     CONSTITUTION: In the control of the electric furnace voltage, the heating temperature is proportional to the heating power (voltage). In this connection, the thyristor is formed into the effective value feedback type to prevent the variation of the control temperature. With application of DC input voltage 40 in the effective value feedback SCR phase control circuit with the polygonal line approximation correction, transistor 41 conducts with the ignition secured to SCR45 and 46. And the mean value voltage emerges across capacitor C59 via feedback circuits 49W58. On the other hand, with increment of split voltage 15W53, the current flows to C59 via diodes 55 and 57 plus resistances 56 and 58. As a result, the voltage of C59 becomes higher than the mean voltage value, and the charging voltage of C59 features the broken line type change at the split voltage point. In this connection, a linear relation can be secured between the voltage 40 and the effective value of load 48 by approximating resistances 51W55 which decide the polygonal line voltage plus resistances 56 and 58 which decide the charging current to the effective value respectively.

Abstract: PURPOSE: To prevent the clogging or the like of a concentrated slurry discharge port to continue good operation for a long time by inclining the surface of a constituting part in a tank body leading to the concentrated slurry discharge port from a slurry inflow port at an angle exceeding the angle of repose of the concentrated slurry. CONSTITUTION: A slurry concentrating tank side plate 19 is installed below a plate 16 attached to a slurry inflow port, and the side plate 19 is straightly inclined and extends toward a concentrated slurry discharge port 9 from the under part of a slurry inflow port 17. The inclination of the side plate 19 is made larger than the angle of repose of a concentrated slurry. Then, the concentrated slurry slips down between an outer plate 3 and the side plate 19 without stagnation and is discharged from the concentrated slurry discharge port 9 to outside a slurry concentrating tank 1. Thus, the clogging at the time of discharging the concentrated slurry is prevented, and trouble-free continuous operation is performed. Besides, the inclination of the side plate 19 is 60 deg. in the figure.  For a gypsum slurry of a stack gas desulfurizer, the inclination is preferably more than 40 deg. because the angle of repose of the concentrated slurry of 60wt.% gypsum is about 40 deg..
